Obesity refers to the phenomenon of excessive body fat, generally speaking, this situation is caused by excessive food intake or changes in human metabolism, which will not only bring bad effects on people’s appearance, but also affect their own bodies. So what are the dangers of obesity? What kind of bad effects will bring to the human body? 1, diabetes According to research, if the body has too many fat cells, it needs the pancreas to secrete excess insulin, and from the blood to sugar into energy. If the pancreas is overloaded, the function will be weakened, and the sugar in the blood cannot be increased, moreover, it cannot be used and discharged to the body, becoming a patient of diabetes. In addition, obese women suffering from diabetes is four times higher than normal women suffering from diabetes, so basically 70 percent of diabetic patients are fat. 2, kidney disease Generally speaking, the kidneys will filter the blood in the human body 25 times a day, so as to remove the waste and toxins in the blood, to maintain the balance of salt and water and other substances in the human body. Once the body is too heavy, it will bring harm to the main organs inside the body. Therefore, most patients suffering from kidney disease are related to diabetes and high blood pressure as well as obesity in the human body. Therefore, it is necessary to properly control their weight. 3, affect pregnancy Because obesity and polycystic ovary syndrome as a causal relationship, resulting in obesity will bring some impact on pregnancy. Because obese people want to get pregnant is already difficult, heart and blood vessels and breathing will be heavier than the general female, once pregnant, the symptoms will also increase, and may cause protein urine. Women with diabetes may also give birth to deformed children. In fact, the harm of obesity is much more than that, but many friends are not aware of obesity itself. For obesity most people have two misconceptions. 1, underestimate the difficulty of weight reduction: heavy obesity patients male weight loss success not rebound less than 1%, and women only 1.5%. However, many people think they are hungry for two days, adhere to the exercise can be “easy” to reduce weight successfully. When not cultivate good habits (or / and) hormone regulation often will greatly obstruct the progress of weight loss; 2, do not pay attention to the hazards of obesity: obesity is often eating patients’ health, many obesity caused by type 2 diabetes patients, heavy obesity polycystic ovary syndrome patients, patients with severe sleep apnea syndrome in the hospital, the doctor may say “it is time to lose weight “. Some friends may complain that the doctor is “irresponsible”, but in fact, weight loss is the most effective treatment plan.
